DNA Testing for Smart Life Choices

Speed vs. Endurance

Do you have a speed or endurance advantage?
Athletic performance is largely influenced by training, coaching, diet and nutrition. However, your genetics also play an important role. Knowing your athletic genetic profile can help you make better decisions about your training and which sports or even positions you should pursue.

Why should you find out if you are destined to be a power or endurance athlete?
Power and endurance activities require different kinds of muscle strength and activity. Genetic testing will reveal your natural advantage. Genetic studies on elite athletes confirm that those with a certain genetic makeup are better suited for endurance activities such as long distance running, while others with a different genetic profile will do better with sports requiring short, powerful bursts, such as sprinting. Testing your DNA for your power or endurance potential will help you choose the right activities or even the team position that is best for you, and will help you optimize your athletic training program.

Genetics 101

Every cell in the human body contains DNA– a long complex chain made of billions of bases called nucleotides. Only four types of nucleotides compose the DNA chain: These are A=Adenine G = Guanin, T=Thymine, C= Cytosine. The DNA chain is packed in 23 separate packages called chromosomes, which make our genome. A gene is a sequence of hundreds, thousands or even tens of thousands of nucleotides. Human cells have two copies for almost every gene in our genome. Together, all of our genes determine our physical characteristics and traits.

Nucleotide sequence in the DNA chain has some differences for each person, which is what makes each of us unique. A change in the sequence of even a single nucleotide can determine a person’s certain tendency. Studies have found that is it enough for a person to have a change in a single nucleotide (known as SNP-Single Nucleotide Polymorphism) to mark a gene and to be able to predict with certainty that this person has a specific tendency.

Athletic Performance – Sprinter vs. Endurance Test

The major protein components of skeletal muscle, which is the type of muscle associated with voluntary movement, are actin and myosin. There are also minor proteins, termed actinins, that bind to actin. The ACTN3 gene encodes one of these actinins, and there is a variation that is very common in the general population. There are no known adverse effects of the variant form of ACTN3, even in individuals who are homozygous (both alleles are identical). However, genetic studies in elite athletes have demonstrated that certain ACTN3 genotypes are associated with either superior power or exceptional endurance ability.

Variations in another gene have also been associated with athletic performance. The NOS3 gene encodes the angiotensin I converting enzyme, a key regulator of cardiovascular function. There are two different versions of this gene, each of which is common in the general population. Like the ACTN3 gene (above), certain genotypes at the NOS3 locus appear to be associated with superior ability in certain types of athletic performance. The physiological mechanisms underlying these correlations are not yet as well understood as for the ACTN3 gene, and future research will undoubtedly clarify these genetic effects. Nevertheless, the correlations with athletic performance are becoming well established, and there are benefits to you in determining your NOS3 genotype at this time.

When you find out your ACTN3 genotype, you can optimize your approach to athletic training and sports based on your natural advantage. You will know whether your genetics give you an advantage in power or endurance.
This test examines the rs1815739, rs2070744 and the rs11549465 markers.

These testimonials are based on fictional accounts, but for most of us, they are all-too familiar situations.

“I decided to run my first marathon a couple of weeks ago and have already started training. My brother, who has run a number of marathons, suggested I take the Athletic Performance: Sprinter vs. Endurance Test to see if I had the same natural advantage for running long distances that he has. I just got my results back and it turns out I do have an inclination towards endurance sports based on my DNA…I guess it runs in the family! No pun intended.”

“I’m competing in the 100 meter race in college and I wanted to see if my DNA supported the fact that this should be my event. Turns out, I am better suited towards short distance running and sprinting based on the fact that the  Athletic Performance: Sprinter vs. Endurance Test showed that bursting power is actually in my genes!”

“I’m restructuring my workouts and want to figure out exactly how to maximize my physical potential and structure my metabolic rate. I’ve been doing a lot of research, but nothing has come close to the information I received after taking the Athletic Performance: Sprinter vs. Endurance Test. I discovered that I am more prone to excel at endurance sports, so now I know that I really have to work on my developing my short my sprinting abilities in order to fully round out my workouts.”
